In recommendation systems, it is usually divided into three stages: recall, sorting, and fusion. The recall phase mainly conducts recall based on different dimensions such as user relevance, information popularity, and local sense; the sorting phase mainly uses clicks, interactions, duration, etc. as goals for scoring and sorting; and the final fusion phase performs overall adjustment of the sequence based on diversity and context.

For the user, the entire browsing information is based on the overall perception of history and context. In addition to the current piece of information, the previous and subsequent information as well as the historical information the user has browsed have a strong perception for the user. Especially in different scenarios, the perception of the overall painting style is stronger. For example, in the two-hop scenario of information flow, the user clicks from a piece of information to enter the two-hop channel. The channel is more about immersive consumption for users and puts more emphasis on overall consumption. The sense of rhythm and fluency, therefore, puts more emphasis on the overall style of painting in immersive consumption.

Currently, in the sorting stage, the overall style is sorted based on goals such as clicks, duration, or interaction. However, there is no unified recall based on the user's drawing style in the recall stage, which makes the information style inconsistent in the recall stage, making it difficult to unify the style in the subsequent sorting stage. . Therefore, how to recall information with a unified painting style becomes the key.

Therefore, an information recommendation method is provided according to an embodiment of the present disclosure, including: obtaining browsed information lists of multiple first users and a first vector corresponding to each browsed information list; The first vector corresponding to the user is clustered to obtain one or more vector clusters and their center vectors; one or more information clusters respectively corresponding to the one or more vector clusters are determined, wherein each information cluster is determined according to The browsed information list corresponding to the first vector in the corresponding vector cluster is determined; in response to the second user's browsing request, the browsed information list of the second user is obtained; in response to determining the second user's browsed information list If the browsed information list is not empty, determine the second vector corresponding to the second user's browsed information list; perform similarity calculations on the second vector and the center vector respectively to determine the similarity with the second vector. matching information clusters; and recommending the second user based on the determined information clusters.

According to an embodiment of the present disclosure, by clustering the vectors corresponding to the browsed information of the user, and performing similarity calculations on the vector corresponding to the browsed information of the current browsing user and the center vector obtained by clustering, the current It provides users with an immersive information consumption experience, maintains the rhythm and fluency of overall information consumption, and improves user experience.

FIG. 2 shows a flowchart of an information recommendation method according to an embodiment of the present disclosure. As shown in Figure 2, in step 210, browsed information lists of multiple first users and the first vector corresponding to each browsed information list are obtained.

According to some embodiments, the first user is an active user, and the active user can be determined based on the following steps: sort the users according to the number of their browsing information from high to low within a preset time period, so as to rank the top 100 preset users. The user corresponding to the quantile serves as the first user.

In this disclosure, the information to be recommended may include, but is not limited to, pictures, text, videos, products, etc. Moreover, in some examples, the information to be recommended may belong to different information categories, such as entertainment, news, sports, etc. Therefore, active users in different categories can be selected respectively as the corresponding first users. Specifically, users under each category can be sorted from high to low according to the number of their browsing information within a predetermined time period, and the users corresponding to the first preset percentile (for example, the top 5%) are taken as the first one user.

It can be understood that other ways of determining the first user are also possible, such as users whose browsing quantity exceeds a preset threshold within a predetermined time period, which are not limited here.

According to some embodiments, the browsed information list includes information identification of the corresponding user's browsed information. Therefore, the vector representation corresponding to the group of information identifiers can be determined based on the group of information identifiers corresponding to each user.

In some embodiments, the vector corresponding to the browsed information list can be obtained through a pre-trained model. For example, set up the two-tower model to be trained, randomly divide the information browsed by the same user into two groups and input it into two towers as positive samples; input the information browsed by different users into two towers as negative samples. The parameters of the two towers are shared, thereby training a two-tower model that outputs the vector corresponding to the browsed information list.

It can be understood that other methods for obtaining the vector corresponding to the browsed information list are also possible, and are not limited here.

In step 220, first vectors corresponding to multiple first users are clustered to obtain one or more vector clusters and their center vectors.

In the above example in which the information to be recommended belongs to different information categories, vectors corresponding to multiple first users in each information category may be clustered. Specifically, for the entertainment category, the vectors corresponding to the browsing lists of active users can be clustered to obtain one or more clusters and the center vector corresponding to each cluster. Other information categories are similar and will not be described again here.

In some examples, vectors corresponding to the first user in multiple information categories can also be clustered simultaneously, which is not limited here. Moreover, in the present disclosure, the first vectors may be clustered based on any suitable algorithm, including but not limited to the Kmeans algorithm.

In step 230, one or more information clusters respectively corresponding to the one or more vector clusters are determined, wherein each information cluster is determined according to the browsed information list corresponding to the first vector in the corresponding vector cluster.

In some examples, after clustering the first vectors corresponding to the plurality of first users, one or more vector clusters are obtained, and each vector cluster corresponds to one or more first vectors. Furthermore, each first vector corresponds to a set of browsing lists of a first user, so one or more information respectively corresponding to the first or more vector clusters can be determined based on its corresponding browsing list of the first user. cluster.

In step 240, in response to the second user's browsing request, a browsed information list of the second user is obtained. In step 250, in response to determining that the second user's browsed information list is not empty, determine a second vector corresponding to the second user's browsed information list.

For example, the second user's browsing request may be the user's browsing operation (such as a sliding operation on the touch screen), a jump operation after clicking on certain specific information, and so on. As shown in Figure 3, the user browses information A, B, C, D... in the browsing page, and clicks information B to trigger a page jump based on information B to jump to information including information B, E, F, G. …view page.

In order for the page after the jump to provide users with an immersive information consumption experience and to maintain the rhythm and fluency of the overall information consumption, after receiving the user's browsing request, it is necessary to recall information with a more consistent overall style to improve user experience.

In order to recall information with a relatively consistent overall style, specifically, in step 260, similarity calculation is performed on the second vector and the central vector respectively to determine the information cluster matching the second vector; and in step 270 , recommending the second user based on the determined information cluster.

In the present disclosure, the similarity calculation between the second vector and the center vector of the cluster obtained through clustering can be performed based on any suitable algorithm, including but not limited to, for example, the annoy algorithm to determine the closest vector to the second vector. One or more clusters.

In the above example in which the information to be recommended belongs to different information categories, the second vector can be similar to the center vector of each cluster under all information categories to determine the second vector in the clusters corresponding to all information categories. A cluster of information that matches the second vector.

In some examples, the information cluster matching the second vector may be a cluster whose similarity is greater than a preset threshold, or may be a preset number of clusters with the highest similarity, which is not limited here.

According to some embodiments, recommending the second user based on the determined information cluster may include: obtaining a browsed information list of the first user corresponding to the determined information cluster; and obtaining the first user's browsed information list based on the determined information cluster. The browsed information list determines a predetermined number of pieces of information with the most views, so as to recommend the second user based on the predetermined number of pieces of information.

Specifically, assume that the browsed information list of the first user A in the determined information cluster is {A1, A2, A3, A4}, and the browsed information list of the first user B is {A1, A2, B1, B2}, The browsed information list of the first user C is {B1, A2, B3, B4. Then after counting the browsed information lists of the first users A, B, and C corresponding to the information cluster, it can be determined that information A1 has been browsed 2 times, information A2 has been browsed 3 times, information B1 has been browsed 2 times, and the remaining information were viewed once. Therefore, after counting the browsed information of all the first users in the determined information cluster, a predetermined number of information with the most views can be determined to recommend the second user based on the predetermined number of information.

According to some embodiments, the method according to the present disclosure may further include: in response to determining that the browsed information list corresponding to the second user is empty, determining the information cluster corresponding to each of the one or more information clusters. Information browsing volume: determine the information cluster with the highest information browsing volume, so as to recommend the second user based on the determined information cluster.

When the browsed information list corresponding to the second user is empty (for example, the second user is a new user), the information in the most active cluster can be directly recommended to the user. Specifically, the number of information views corresponding to each information cluster can be determined based on the method described above. For example, a certain information cluster includes information A1, B1,...,N1, and it is statistically determined that information A1 has been browsed a times, information B1 has been browsed b times,..., and information N1 has been browsed c times, then this information The number of views corresponding to the cluster is a+b+…+c. Thus, the information cluster with the highest number of information views among the one or more information clusters is determined and recommended to the second user.

According to an embodiment of the present disclosure, as shown in Figure 4, an information recommendation device 400 is also provided, including: a first acquisition unit 410 configured to acquire browsed information lists of multiple first users and each browsed information The first vector corresponding to the list; the clustering unit 420 is configured to cluster the first vectors corresponding to the plurality of first users to obtain one or more vector clusters and their center vectors; the first determination unit 430. Configured to determine one or more information clusters respectively corresponding to the one or more vector clusters, wherein each information cluster is determined according to the browsed information list corresponding to the first vector in the corresponding vector cluster; The second obtaining unit 440 is configured to obtain the browsed information list of the second user in response to the second user's browsing request; the second determining unit 450 is configured to respond to determining that the browsed information list of the second user is not is empty, determine the second vector corresponding to the second user's browsed information list; the third determination unit 460 is configured to perform similarity calculations on the second vector and the center vector respectively to determine the similarity with the second vector. the second vector matches the information cluster; and the recommendation unit 470 is configured to recommend the second user based on the determined information cluster.
